Documents that match how you sell
Invoices, quotations, delivery challans, credit notes, and purchase orders — create, duplicate, preview PDFs, and convert quotes to invoices without re-keying.
Product
GST billing, simplified.
Invoice Management System — a SaaS platform for Indian businesses that need compliant billing, reliable payments, and operational depth without running finance out of inboxes and sheets.
Hosted separately at ims.techtrio.net. This page is the marketing overview; the app has its own pricing, auth, and support flows.
Why IMS
IMS is our owned-and-operated billing stack — not a white-label reseller. We ship features the same way we ship client work: iteratively, with clear boundaries on what is production-ready today.
Invoices, quotations, delivery challans, credit notes, and purchase orders — create, duplicate, preview PDFs, and convert quotes to invoices without re-keying.
CGST, SGST, IGST, HSN/SAC, place of supply, reverse charge, and multi-rate GST. Razorpay, Stripe, and PayPal — payment links, reminders, and subscription plans with trials.
Products, inventory, warehouses, stock transfers, expenses, projects, time entries, clients, and vendors — with dashboards and reports for revenue, tax, aging, and cash flow.
Multi-tenant org structure, RBAC, SSO options, API keys, audit logs, sessions, rate limits, and Redis-backed performance — the kind of foundation finance ops expect.
Full web app plus React Native (Expo) apps for iOS and Android — OTP login, biometrics on device, and the same core flows on the go.
GSTR-1 / GSTR-3B views and exports are still maturing. NIC e-invoice (IRN) and integrated e-Way bills need GST portal API access. We label what is live vs in progress.
Need implementation help, migrations, or custom integrations around IMS? That is what our services team is for — same company, clear handoffs.
